Preamble
My Ubuntu box displays very few connected devices automatically. As this Wiki hoster provides some ways to markup I'll use this site to document what I have tried.
The computer runs Oneiric Ocelot.

It seems to be associated with me having an old card reader unprepared for bigger capacity cards.
After plugging a 512 MB card, dmesg reads:

multiple times, but GUI offers the three options as expected.

Conclusion
Send in camera, buy current card reader (or try card slot on desktop box), power connect USB port.
